JetBlue Airways is bringing back their famous two-day fare sales — this time with $44 one-way flights for fall travel.

Encouraging travelers to “get the fall rolling” on autumn and winter getaways, the sale is valid on flights between October 17 and December 14. (Blackout dates include Thanksgiving, as well as November 7 to November 13 from select airports.)

The most inexpensive flights are between Long Beach, California and San Francisco, and from Fort Lauderdale to Chicago. Both are $44 one-way.

For $59, Boston-based travelers can fly to and from Atlanta, while Charleston is accessible for the same price from Washington, D.C.

If autumn foliage and spiced apple cider are a requisite for your fall vacation, there are $69 flights from New York City to Burlington, Vermont or Portland, Maine, and $49 flights from Long Beach, California to Lake Tahoe.

Of course, travelers more interested in fleeing the fall chill can instead book warm weather getaways to Bermuda, Florida, North Carolina, Georgia, and New Mexico for $100 or less.

JetBlue reservations must be made by 11:59 p.m. EST on October 5.
